The main objective of our research was to compare followers evaluation of Polish middle managers in regard to their traits and behaviors, which are essential for leadership effectiveness, in the years of 2008/2009; 2010/2012; 2012 and during 1996/1997 under the GLOBE research project. As was unexpected, our research results indicate the Polish middle managers under our follow-up study scored significantly lower than their counterparts investigated under the GLOBE study in 1996/1997 on Performance Orientation, Team Orientation, Humane Orientation, Integrity, Visionary and Inspirational Leadership Dimensions, and significantly higher on Autocratic Leadership style. Our findings point to the conclusion that profound changes in political and socioeconomic systems in Poland, have shown little effects so far on managerial values and subsequent attitudes and behaviors. We postulate that deep changes in peoples’ mentality are needed to generate beneficial changes in the societal and organizational values and succeeding attitudes and behaviors.
